The US-led coalition against so-called Islamic State (IS) says one service member has been killed and a second injured in a roadside bombing in Iraq.
An improvised explosive device (IED) struck their vehicle on Sunday, according to a statement.
The names and nationalities of the casualties are being held until their families have been notified.
Seven US personnel have been killed in Iraq since 2014, including two in the battle to retake the city of Mosul.
A French soldier was also killed in the fight against IS last month, although it is not known if he died in Iraq or Syria.
The non-commissioned officer from the elite 13th Parachute Dragoons Regiment was advising local forces when they came under fire.
